Why is full screen FPS high? Analyze the key factors for improving frame rate

In the field of games and video playback, the frame rate (FPS) in full-screen mode is often higher than that in window mode, which has caused many users to question. This article will analyze the reasons for high full-screen FPS from the three dimensions of hardware, software and system optimization, combined with hot topics and hot content on the Internet in the past 10 days, and provide structured data support.

1. Hardware performance release

In full-screen mode, the GPU can allocate resources more efficiently. The following is a comparison of recent popular hardware test data:

2. System-level optimization mechanism

According to Microsoft’s official technical documentation and recent developer forum discussions, full-screen mode enjoys three major privileges:

3. Differences in software rendering pipelines

Through analysis of recent update logs of Unity and Unreal engines, the full-screen mode rendering path is shorter:

1.Reduce compositing overhead: Eliminate the window manager composition step
2.Simplify buffer exchange: Flip mode replaces Blit copy
3.Exclusive display control:Avoid sharing GPU cycles with other applications

4. User test cases

Collecting high-like discussions in Reddit and Tieba in the past 10 days, typical configuration comparison:

5. Exceptions for special situations

Note that the following situations may break the rules (data comes from recent bug reports):

1. Multi-monitor extended mode: full-screen FPS may drop by 8-15%
2. HDR enabled status: some game window modes exceed 5-10%
3. Win11 22H2 version: There is a known issue in which full-screen optimization fails.

Conclusion and recommendations

Based on the technical discussions and actual measurement data in the past 10 days, the core reasons for high full-screen FPS are:Rendering pipeline shortening + hardware resource exclusive + system privileged access. Players are advised to:

1. Full-screen mode is a must-have for competitive games
2. Creative software can test borderless windows
3. Check the graphics card driver version when encountering an exception (there is a full-screen bug in the recent NVIDIA 536.99 driver)
